The Tax Unit (TU) is a referential value created by the Organic Tax Code in 1994 to update tax bases, fees, fines and similar tax concepts according to the annual inflation. The National Integrated Service of Customs and Tax Administration ("Revenue Service"), upon approval of the Permanent Commission of Finance of the National Legislative Assembly, must adjust the TU based on the variation of the National Consumer Price Index published by the Central Bank of Venezuela for the prior year.  

Despite the fact that the Organic Tax Code provides for the annual adjustment of the TU, the Revenue Service adjusted the TU four times in nine months from March 2018 until the end of that year, without the approval of the National Legislative Assembly.  

In less than six months, in 2019 the Revenue Service has once again adjusted the TU value to 50 Sovereign Bolivars (VES), and, like in the past, without the National Legislative Assembly's approval, as summarized below:  

Adjustment Days in force
  1. The first time was on 1 March 2018 from VEF 300 to VEF 5001. That value was in force from 1 March to 1 May 2018.
61 days during 2018
  1. The second time was on 1 May 2018, from VEF 500 to VEF 8502. That means the Revenue Service considered a 70% inflation between 1 March and 1 May. That value was in force from 1 May to 19 June3.
49 days during 2018
  1. The third time was on 20 June 2018, from VEF 850 to VEF 1,2003. That means the Revenue Service considered an inflation of 41.7% between 1 May and 19 June. That value was in force from 20 June to 10 September.
82 days during 2018
  1. The fourth time was on 11 September 2018, when the new currency was in force, the Sovereign Bolivar (VES)4, from VEF 1,200 to VES 17.00 (VEF 1,700,000)5. That means the Revenue Service considered an inflation of 1,416% between 20 June and 10 September. The new value is in force since 11 September 2018.
112 days during 2018 and 64 days during 2019
  1. The first modification in 2019 was on 7 March from VES 17.00 to VES 50.006. This means the Revenue Service considered an inflation rate of 194.11% between 12 September 2018 and 7 March 2019.
 

Considering the Central Bank of Venezuela has not published the National Consumer Price Index since December of 2015, different reliable sources have estimated the inflation for 2017 between 2,616%7 and 2,735%8 and the inflation for 2018 in 1.299.724%9, the value of the TU is divorced from reality. Something similar occurred in 2016, 2017 and 2018.

In cases of taxes determined annually, such as income tax, the TU value will be the one in force for at least 183 consecutive days during the period. For taxes determined other than annually, such as VAT, the TU will be the one in force at the beginning of the period.  

The TU adjustment will only apply for determining national (federal) taxes administered and collected by the Revenue Services and the fines imposed by such office.  

The adjustment of the TU increased in approximately 194% other concepts, such as the tax base of taxes and fees. The most important are:

Maximum income tax rate:   (Individuals, Tariff No. 1: 6,000 TU) (Legal entities, Tariff No. 2: 3,000 TU) Individuals: 34% on the portion of net income over VES 102,000 Individuals: 34% on the portion of net income over VES 300,000.
Legal entities: 34% on the portion of net income over VES 51,000 Legal entities: 34% on the portion of net income over VES 150,000
